- 38-year-old Leo Varadkar's father moved to Ireland in 1970s
- Varadkar will be first openly gay PM of once-staunchly Catholic country
- Varadkar was first elected to the parliament in 2007
Varadkar's election as leader of the governing Fine Gael party on Friday means he will almost certainly succeed Enda Kenny as prime minister in the coming weeks, marking another symbolic moment for Ireland.
"If somebody of my age, of my mixed race background and of all the things that make up my character can potentially become leader of our country, then I think that sends out a message to every child born today that there is no office in Ireland that they can't aspire to," Varadkar told Newstalk radio this week.
The fact the milestone of electing a gay premier is barely mentioned in local media and has taken place -- in the words of one former government minister -- "without anybody batting an eyelid" shows just how far Ireland has come.
Instead, after six years of Kenny's steady stewardship, the focus has been on the stark change of style likely to follow the election of a minister known as a straight talker. Colleagues giddily proclaim that their new leader has the 'X Factor'.
Varadkar had not been born when Kenny, 66, was first elected as a member of parliament and comes from the generation hit hardest by Ireland's economic meltdown. He owned an apartment that fell into negative equity at the turn of the decade.
He will also be a year younger than France's Emmanuel Macron when he attends his first EU leaders summit later this month. But Varadkar has been quick to point out that the favourite to become Austria's new prime minister, Sebastian Kurz, is eight years younger.
"He's a once-in-a-generation politician," said Fine Gael member of parliament Jim Daly, echoing the comments of most of his colleagues who have placed high hopes in Varadkar.
Such a dramatic change of style could go two ways, analysts warn. Varadkar's tendency to shoot from the hip can backfire. As a novice minister he said Ireland would likely need a second bailout six months after signing its 2010 EU/IMF package.
"When you're Taoiseach (prime minister), you can't speak as open and freely as when you're a maverick, straight-shooting minister. If he doesn't temper his more colourful contributions, that could actually become a liability quite quickly," said Theresa Reidy, a politics lecturer at University College Cork.
She said that although he has held three cabinet post since 2011, Varadkar is relatively inexperienced. With the exception of Kenny, every prime minister since the 1960s either served as finance or foreign minister prior to taking office.
Kenny sat in parliament for 35 years before his elevation. Varadkar was first elected in 2007.
Seen as being on the right wing of the centrist Fine Gael, Varadkar also upset Ireland's left with a recent publicity campaign highlighting social welfare fraud.
And his management style will be tested by Fine Gael's weak minority government that is backed by independent lawmakers and facilitated by the main opposition party.
As someone who once described himself as not being "a natural people's person", the trained doctor will need a good bedside manner.
"We don't really know how he will react under pressure and it is different when you're Taoiseach," Reidy said.
